From the news release:
Georgia Department of Transportation (Georgia DOT), The Ray, and the University of Georgia’s College of Environment + Design (UGA CED) are pleased to provide a major update to the living vegetative lab spanning the diamond interchanges at Exit 6 on Interstate-85. Throughout January, UGA CED, led by Associate Professor Brad Davis and MLA candidate Mathew Quirey, installed additional pilots: the testing of non-chemical weed control and new mixes of native wildflower and grass seed designed to provide continuous and successive blooms from late spring to early fall.
